Labs / SSRF Validator
- Daily Challenge
- Released 02 Oct 2025
🌐 Can you trick the server into revealing its own secrets?
A seemingly secure URL validation service stands between you and sensitive internal data! 🔒 The server thinks it's safe behind its firewall, but clever request manipulation might just convince it to fetch data from places it shouldn't. 🕵️ Master the art of server-side request forgery and turn the server against itself! 💥

🌐 Server-Side Request Forgery (SSRF) Exploitation
Server-Side Request Forgery (SSRF) is a critical web vulnerability that allows attackers to make requests from the server to internal resources or external systems. This challenge simulates a URL validation service that can be exploited to access restricted internal endpoints.
🎯 What You'll Learn
- ✓ SSRF attack vectors and techniques
- ✓ URL parsing and validation bypass methods
- ✓ Internal network reconnaissance
- ✓ Protocol manipulation for SSRF exploitation
🔍 Challenge Overview
You'll encounter a web service that validates URLs and fetches their content. The service has security measures in place, but these can be bypassed using various SSRF techniques to access internal resources and retrieve sensitive information.
